No, it can't figure it out itself.  It can't view the source code of your 
program, it doesn't know how large your variables are.

Remember, parameters are passed as a pointer. That's all the program 
that's receiving the parameter gets, just a pointer, nothing else. How 
does it know how long the variable is?

There are two possible ways to solve that problem:

a) You can pass it a length.  (That's the solution that QCMDEXC uses)

b) You can pass some sort of delimiter to indicate the end of the string. 
(that's what system() uses)
